its indicatorstrip 6 may of course be easily known, so that the device'may. be clampedinto the properposition on the graduated support for the gauging operation. With the assemblage thus dipped into the liquid, and the end of the graduated support in contact with the bottom of the tank, the total height of the liquid is accurately registered on ated rods or tapes.

the indicator-strip 6,. and after withdrawal, may

be read off on the calibration of the graduated support. By reason of the absence of creeping,

and the absence of loss of'efiect by evaporation from the indicator strip, the liquid-level line is accurately shown, without errors such asihereto' fore encountered by, the mere dippingof ,grad

By suchJarrange- I ment, after an exposedlength of'the strip fi'has beenv used-, the strip may be drawn down further, and-tl eused surplusfbelo'w maybe tornofL 1 1 Instead of aiormof clampin'g meansjrequiring screw-threaded settingji may in some cases" employ'a frictionally held form; as for: instance in Fig. 5, a spring-engagement for the semi-housing members 9b, the tongues 3b, 4b, 5b,- having the relation; as afore-described. The spring means,

desirably also instead-of being a'-'s'eparate spring element, may be-combined'a'sthe bar 2b itself. That is, the latter is given a set suchth'at it has to r be slightly deformed in orderto assemble the semi-housings 9b on the graduated support-1c,

and when in such position, the 'resiliencyof the bar 2b holdsthe device'tight byfrietional engage-'- inentl The indicator-tape is threaded' through and held by the tongues f3b,'t4 b,i5b, as already described; I In some cases, instead of'a longitudinal spring element on the lines showninfFig; 5,,Imay apply bow-string elements'at each 'endof-theibar and transversely thereto, as shown irij igs fi and? particularly.- The semi-housing 9c carriesjolj provides tongues 30, 50,. while the 'bow-spring ele ,inent 4c provides the intermediate. tongue,; and

As thus seen, gauging gas for instance} oi'inotor 'fuel lor other hydrocarbon 1 products, may be 'quickly' and 'j conveniently and accurately per ,iformed.
